Las Vegas loves a second-chance story. Apparently TikTok does, too. This social media sensation begins at an amusement park where a handful of kids die on a roller coaster called the Cyclone (likely because the real Cyclone at Coney Island feels like it may actually kill you). Once in purgatory, they’re greeted by the park’s mechanical fortune-telling machine, which initiates a singing contest that awards the winner a trip back to the living world. What ensues is a competition that alternates between morbidity and life affirmation — and hopefully bears no resemblance to the reality TV singing shows your mother still watches. Chalk up another staged celebration of cult pop culture and viral theater by Majestic Repertory.
